"Presented are the results of experiments focused on the study of thermal treatment influence of selected black coal fly ash from the heating plant in Ko\u0161ice. Study was realized with the original not pre-treated fly ash sample and sample with Al additive in different mixing rates. The obtained results confirmed that after the thermal treatment occurred the phase's change of the material. By the 1050 \u00B0C degree there was the decrease of amorphous phase remarked that was transformed on the mullite and corndum. This information allowed the possibility to use the examined fly ash sample as a matrix for the mullite composites preparation providing the stoichiometric change of thermaly treated mixture."@en . .
